I'd go with a set of 906's because of the superior port design, or 915's for the good ports and added squeeze. You can use a stock 318/727 torque converter for a little more stall for cheap.

Meep-meep, not to stir the pot inside a great conversation on cam shaft selection, but everything I have read (and heard) so far indicates there is nothing wrong with the 346 or 452 head castings (which are likely on Boz's 440), in fact they may be a better choice due to the hardened seats for todays fuels. I have posted in another thread, flow bench results on all 915, 906 and all of the "smogger" heads done by Mopar muscle magazine. Here are the links:

Btw, I do not profess to be an expert on engine and driveline, thats why I am here!

By far the laziest camshaft I've come across in over 30 years...much..much..much better choices out there.

Funny, but I have had similar experience with the .484 cam. I think it needs compression. The .474 has been nothing short of spectacular. I used to run an Isky .465" 280 deg in a 383 and it was great too.

No sweat. It's all about sharing experience and knowledge. I'm just reporting on what I've done and read over the years. I spent a lot of time reading the factory performance bulletins and tried to apply that thinking to my own cars. I'd say I was doing well with my little 383 in a 68 RR back in the day. Like I said in another post; it's all about getting the atomized fuel in to the cylinder (wet flow) and however it's done is good enough. It's also about creating the most average HP over the usable RPM range, and the only way to know for sure is to keep changing parts and recording the results in a scientific manner. You just gotta get your hands dirty. My 66 Belvedere is going to be my seat of the pants dyno.

BTW, the links didn't work for me.
